IMO it's fair enough for low-level processes to assume continuity of
power. Having (and regularly testing) an appropriate UPS is a baseline
component of any system where reliability is important.
Perhaps a re-wording: You will more easily be able to recover your
data in the event of a system crash if your LVs don't span multiple
PVs.
